Further musings on the Fender Amp no reverb problem

Hey robotek, Thanks for helping so far. I have new input for you on the problem. I unplugged the foot switch and the reverb works fine. I then trouble shot the foot switch by jumping the wires (bypassing the switches themselves) in the foot switch. The vibrato side worked but the reverb sided didn't. What I gather from this is that it is NOT the switch because I doubt the wires are the problem. So the reverb unit works without the switch. When the switch is pluged in, the vibrato side works but the reverb side doesn't. I obviously want to use the switch when onstage. What do you think? Thanks, Blownhead

Hi, sorry for the delay. Sounds like a faulty cable, or the termination at the jack plug is faulty. These can create the problem you have. What model do you have again, don't remember getting that from you.

cheers

Is there a way to make the sound of the reverb on my deville 2-12 sound better ?


modding the reverb takes some electronics experience...if you know where the reverb circuit is. all you can really do is change the input caps that make the tone bright or dull... larger uf for dull... lower cap values for bright... it's in the signal circuits... dont mess with power caps. The schematic shows op amp into the tank and out of the tank to another op amp...Output of the tank to opamp.. Id double that input cap ( 330 pf ) to see if you get more response into the opamp... then look at the circuit C17-C18/R33-R34 894cf4a0-46f7-4f21-9667-be620f05b31d.png

What year would a Fender Princeton Reverb with serial number A08011 be? Thanks!


Deciding the date depends on what part of the amp your serial number is.

I have a brand new fender deluxe combo amp is the preamp in and out usable for an effects loop


Yes you could do that. The preamp output is just a BUFFERED output of the signal sent to the power amp. And the power amp input jack is BUFFERED before driving the power amp. These impedances are neither high or low being in the 1K to 3K ohm range.

The jacks for BOTH are mono jacks so noise pickup is possible if long cables are used. The external effects unit should be well grounded and operate off the same receptacle as your Fender for system safety. Use SHORT audio cables to minimize noise.

ALL the signal will pass through the effects unit when used this way... HOWEVER the internal reverb will still be in this path. You can kill this by turning the reverb control to zero on the Fender.

Reverb wont work !!!!!!! Hot rod deville 410


probably a bad reverb tank. there is a little inductor inside that shorts out easily/common. you cant repair it. its just easier to order a new tank. what you do to test is........turn on the amp with the reverb turned up all the way........ volume up on the amp at normal playing level.....then tap or knock on the reverb tank itself......if you get sound then the output of the tank is good/ no sound the ouput side is dead.......then what you do is unplug the ouput of the tank and plug the output wire to the input of the tank and tap/knock on it again....if you get sound then the input side of the tank is good/ no sound is dead. this is a way to test the tank independently from input to output. which side is bad is irrelevant, what is improtant is determining if the tank is toast. i can get accutronics tanks from my distributor at a better price than anywhere else. email me thru my contact page on my website with the tank code numbers and letters so i can get you a price also check my price with whats on ebay, etc. my website is yostamplifier.com
good luck

HELLO, just bought a fender HRD 410 AMP AND DISCOVERED THAT THE REVERB DOES NOT FUNCTION ! WHAT'S UP ?


Hi Fenderman.

Damn, you gotta hate that. First thing, do you have any recourse with the outfit you just bought the amp from? I guess not if you are asking in here. There is not a whole lot that stops the reverb in these amps. First things to check would be that the connections to the rev-eb tank are ok, and the cables to them not damages, and the terminations to the RCA plugs are good. Check that the reverb tank is connected thew right way round also. If everything so far checks out, and yourself, or an electronics savvy mate then time to download the circuit from here

Then from there, pull the chassis out of the box, and check/look for dry/cracked solder joints about the reverb Pot, I would check the voltages about U2, TL072, and even just change it out if you are unsure. The reverb tank could also be down, hard to check this easily without swapping it out, if you have(maybe time for the repair shop here) a CRO, then you can sniff off the audio going in and out of the tank to be sure that is it functioning.

Anyway, that is a rundown on what may be wrong with the HRD. If you have any questions, more that happy to answer them and continue to help you out. a FixYa rating is a great reward for my time to talk this through with you. Cheers!

I have a Fender tube amp The Twinn. 4 6l6 2 12at7 and 4 12ax7. Mu reverb is dead and I here some strange oscillation. I suspect the 12at7 in reverb and one 12ax7 Both microphonic and very dem fil. ...


Hi ohmytom

Yes, they could be causing the problem.The filaments are a little hard to see sometimes, you will always get a little microphonic activity about preamp tubes. It may also have failing capacitors depending on how old it is. Is it a "Twin Reverb". Let me know the exact model and we can be a little more specific of the problem and solution. Cheers

Fender deluxe reverb


Hi Hoopnholler

I would start by changing out 12AT7 (V4), is a common buffer stage to the vibrato and reverb audio path. If you have trouble identifying it, you can just swap out with a known good tube and see if it resolves your problem.
If that does not help, then time to go see an amp doctor. If youy are inclined. here is a circuit diagram that you may find useful in faultfinding the problem yourself.
.
I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.
